Matthew Poole and continuators on 1 Samuel 19:11

11 Saul also sent messengers unto David's house to watch him, and to slay him in the morning : and Michal Davids wife told him, saying, If thou save not thy life to night, to morrow thou shalt be slain .

Why not in the Night? Ans. Partly, because it would have been barbarous, and most dishonourable to Saul, to break into David's House by Night, and kill him in his own House and Bed; and it seemed more expedient to kill him as he came out of his House in the Morning: partly, because the Night might give David some opportunity of escaping, which the Day-light would prevent: and principally, by Gods singular Providence, infatuating Saul's mind to take the worst course, that David might be delivered from him.

Which she might learn, either by information from Ionathan, or some other Courtier that was privy to the design: or from her own observation of some suspicious or dangerous Persons hovering about the House.
